Just a small reminder...You can cook two or three or 6 butts in your WSM in that 10 hours, and it freezes well (really, really well if you vacuum pack too), so unless you are practicing your fire control skills, I would always cook more than you are planning on using immediately.
One of the other things I do, is to offer my close neighbors the chance to add a butt or two for themselves, they pay for their meat and buy the charcoal for mine
, what a great deal that is; all round!
I rarely do less than four or five butts this way and that gives us two or three and the neighbors one or two butts cooked at the end of a day.
The other thing I do once every couple of months, is to clear out the freezer, I have it marked every 8 weekends on a calendar in the kitchen. I always date and label everything that goes in, so I can see quickly if things are over 2 months old, I donate to our local firehouses a pack of pulled pork, there are 5 firehouses on my drives to work or the stores, and I rotate which one gets the package, if I have more than one package I drop them at more than one firehouse. The firemen have yet to turn down a vacuum package of pulled pork in sauce. They sure appear to relish the drop off early in the day, I will mostly drop packages off about 7:50 AM this gives them plenty of time to choose which meal in the day they are going to use it for, or if they are going to keep it frozen and have it the next day.
